This is my first ever time asking a question here, so bare with me if something's not right.
So, I don't understand this whole problem, and if anyone is willing to explain it, i'd be really thankful
So there is a circular track of $6 \text{km}$. There are $3$ objects moving with $40 \ km/h, 55 km/h $, and $\frac{100}{3} \ km/h$ respectively. The track is divided by points $A,B,C$. $AB=3km \ , BC=1km ,\ AC=2km$. All objects move counter clockwise. the $1^{\text{st}}$ object starts from the point $A$, the $2^{\text{nd}}$ from point B and the $3^{\text{rd}}$ from point C.
And I need to find time) of their first meeting point (no matter where on the track but they all have to meet). The time is in hours, and is a natural integer.
Thank you beforehand.
